Re: [Ltib] gdb-6.6 build problems

[Stuart Hughes]

Hi Vadim,

I took this off-list with Ned due to the attachments, but attachments
aside I've in-lined the email below.

Curiously -Werror has always been there, so it looks as though some host
related component is leaking in from the updated Ubuntu? whether there's
a difference in the configure results triggering this, or something else
I don't know.

Maybe you could try the steps and let me know what you see?

Regards, Stuart

Hi Ned,

I've taken this off the list until we resolve it as the attachments are
a bit big.

This has got me a bit stumped.  I just build the default configuration
for the imx27ads using the current sources at Savannah CVS.  I don't get
any build errors.

Looking at the log, the build command for that file is the same, so
I'm guessing that somehow you're pulling in a different header file from
me.  Did you change anything from the default?

Anyhow, can you try this:

$ ./ltib -m shell
LTIB> cd rpm/BUILD/gdb-6.6/cross-gdb/bfd
LTIB> gcc -DHAVE_CONFIG_H -I. -I../../bfd -I. -I. -I../../bfd
-I../../bfd/../include -W -Wall -Wstrict-prototypes -Wmissing-prototypes
-Werror -g -O2 -c ../../bfd/elf32-arm.c -o elf32-arm.o -save-temps
LTIB>

If you look at elf32-arm.i, search for asprintf and then go back and
find where it gets included from.  Mine is
from 
/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/arm-none-linux-gnueabi/sysroot/usr/include/stdio.h

I've attached my preprocessor file elf32-arm.i

Note to exit the ltib shell, type 'exit'
